Guild Wars 2

I went threw about 20 or so of them and only have 1 mastery unlocked. What am I missing?

thanks

The fact that the scolls give heropoints for the specializations, not exp for the masterys.
If you want masterys you have to do PvE

Each time you use one those scrolls, you finish one uncompleted Hero Challenge. They provide nothing toward mastery.

I know if you finished all the HPs of central/old Tyrian you can’t even buy that version of the scrolls, but what if you have a few not finished? Example you have 4 un completed HPs, can you buy more than 4 scrolls? Anything after 4 is useless (in this example)……

Now if we could pick the HP (like the bat guano in verdant brink)……

thanks, I think that clears it up a bit
